inve tion relates to improvements in i cnsils and more particularly in a and it the principal object of .nventien to provide a boiler top equipped c wi h means {or autoniiati ally indicating the that the contents of the boiler are about or my invention will become more fully known as the description thereo'l proceedsp and will then be specifically pointed out my 20 the appended claims.

a material part of this disclosure:

1 is sectional side elevation of a boil r having a top equipped with the acoustic signalling device constructed according J to my invention. 7

w s a sectional side elevation of a top 1 enlarged scale.

a ver 10 of any suitable shape and material, :lor instance as shown, of substantial triangular shape for :t'acilitating the pouring out o'l its contents has a handle 11 attached to one of its sides. The top of the vessel is closed by a cover 12, slotted as at 12, and havmg a lower llange or head 13, and attached thereto the bars A and 15 which are connected at their upper ends by a handle bar 16 made of heat insulating material.

The cover 12 has an upper inner flange 17 and a lower inner flange 18 spaced therefrom.

Between the two flanges a membrane 15) is held having a convex-concave central diais a cross-section on line 33 of" Serial No. 23,068

phragm member 20, provided with an upper opening 21 and a lower opening 22 in approximately the middle thereof in alio'nment, and one or these openings is pr rably wider than the other. l SLlTWlSQ arranged rain-discs S23, are exchangeably secured by headed bolts 25 and 26 to the diaphragm member 20 and have rounded recesses 27 and in their margins allowing a change in the width of the opening 21 and 22 to change the tone oi the whistling sound pro duced by the escaping steam or vapor passfrom the vessel to the atmosphere.

it will be clear that the cam discs may be exchanged to allow a change in the width of the openings and may be secured either The operation of the device will be en j rely clear from the above description and in the accompanying crawin forming-r l'il lS'llO be understood that such changes may be made in the preterred i orm illustrated in the drawing, such as fall within the scope of the appended claim without departure from the spirit ot' my invention.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent, is:

in a cooking utensil of substantial triangular shape having a restricted neck part, a handle, a slitted and flanged cover tor the utensil adapted to snugly engage said neck, a diaphragm held between the flanges of said cover, and having a perforated convex-concave central member, cam iaces having re cesscs adapted to be secured on top and below said diaphragm and adapted to increase and decrease the width ol' the openings there in for changing the whistling sound made by the steam escaping from the utensil through the perforations in the diaphragm to give an acoustic alarm.
